    摘要: The present disclosure provides a quantum dot ink, a color filter film, a display device and a color filter film preparation method, the quantum dot ink comprises quantum dots, siloxane and an acrylate compound, the quantum dot ink contains 1-50 wt % of the quantum dots, 5-50 wt % of the siloxane, and 10-90 wt % of the acrylate compound, wherein the siloxane is used to generate polysiloxane microspheres. When the siloxane is subjected to a reaction, so as to form the polysiloxane microspheres, which may reflect light that is not absorbed in the quantum dots such that the reflected light is re-absorbed in the quantum dots, so as to increase the amount of light absorbed by the quantum dots, thereby improving the light-emitting brightness of a color film prepared and formed in the quantum dot ink, effectively enhancing low utilization of excitation light, and improving a display effect of a display device.

    摘要: The present disclosure provides nanoparticle transducers and methods of use thereof for the detection of analyte concentrations in a fluid. Nanoparticle transducers can comprise a nanoparticle, such as a Pdot, coupled to an enzyme that catalyzes a reaction with the analyte. The nanoparticle transducers further comprise chromophores that emit fluorescence that varies as a function of the concentration of one of the elements of the reaction. The nanoparticle transducer thus changes fluorescence as the analyte concentration changes, transforming analyte concentration values into fluorescence intensities. The measurement of these intensities provides a measurement of the analyte concentration. The nanoparticle transducers are biocompatible, allowing for use in vivo, for the monitoring of analyte blood concentrations such as blood glucose concentrations.

    摘要: The disclosure features methods of analyzing a fluid extracted from a reservoir, the methods including introducing a first composition featuring a first complexing agent into a reservoir at a first location, extracting a fluid from the reservoir at a second location different from the first location, combining the fluid with a second composition featuring a concentration of a lanthanide ion to form a third composition featuring a concentration of a complex formed by the first complexing agent and the lanthanide ion, exposing a quantity of the complex to electromagnetic radiation for a first time period ending at a time t0, detecting fluorescence emission from the quantity of the complex for a second time period starting at a time t1>t0, where t1−t0 is greater than 2 microseconds, and determining information about a fluid flow path between the first location and the second location.
